QUICK-ACTIN G PITE-VISE.

Application filed May 18, 1914. Serial No. 839,345.

Specification of Letters Patent.

To" all whom it may concern:

Be it known that I, FRANK J. CALLAN, a citizen of the United States, residing at Boston, in the county of Suffolk and Statev of Massachusetts, have invented a new and useful Improvement in Quick-Acting Pipei-Vises, of which the following is a specification, reference being had to the accompanying drawings.

This invention has for its object to provide a vise the jaws of which may be quickly closed and opened and are automatically locked when closed, the jaws being preferably adapted to hold cylindrical bodies, and the vise being especially adapted for the use of plumbers.

The invention consists in the improvements which it will now proceed to describe and claim.

()f the accompanying drawings forming a part of this specification: Figure 1 represents a side View of a vise embodying my invention, the jaws being closed upon a length of pipe; Fig. 2 represents a similar view, showing the jaws opened; Fig. 3 represents a top plan view; Fig. 4 represents a section on line l-t of Fig. 2, looking to- :ward the right; Fig. 5 represents a section on line 5-5 of Fig. 3; Fig. 6 represents a section on line 66 of Fig. 2, looking toward the right; Fig. 7 represents a perspective view of one of the jaw facings hereinafterreferred to ;-Fig. 8 represents a plan view of the adjustable toggle link shown by Figs. 1,2 and 3, the nut portion thereof being in section; Fig. 9 represents a side elevation of a modified form of operating lever.

The s.;me reference characters indicate the same or similar parts in all the views.

1 represents a fiat base adapted to be attached to a bench or other support and provided at one end portion with a fixed jaw 2, and at the opposite end portion with a fixed standard spaced at a considerable distance from the fixed jaw, and preferably composed of two spacedapart side members 3 connected by a transverse web 3. The base 1 is provided, between the fiXed 'j aw and the standard, with longitudinal. guides 4, withwhieh are slidingly engaged grooved ears or runners 14: formed on or attached to a mov able jaw 13, opposed to the fixed jaw 2. The opposed sides of the jaws 2 and 13 may be provided with coinciding recesses 6 and 7 adapted to receive lengths of pipe of dlfierent diameters, said recesses being preferably formed in Babbitt metal face plates 5 having flanges 9 which are screwed to the ends of the jaws. Said cavities may have grooves 8, as shown by Figs. 5 and 7, to hold resin or other frictional material.

The movable jaw 13 is connected. with the fixed standard 3 by a toggle, one of the links of which is preferably adjustable in length, and is formed as a turnbuckle composed of oppositely screw-threaded sections 19 and 20, and anut 21 threaded to engage said sections. The section is connected by a pivot or knuckle pin 26 with the other link of the toggle, said link being preferably Patented Sept. 29, 1914.

composed of two members 30 connected by a hub 30* (Fig. 4). One end of the toggle is connected by an outer pivot 17- with an ear 16 on the movable jaw 13, and the opposite end of the toggle is connected by an inner pivot 28 with the standard 3. The pivots l7 and 28 are in a plane substantially parallel with the base 1, so that the toggle, when in its active position with its links in or approximately in alinement with each other, stands substantially parallel with the base.

31 represents a manually operated operating lever connected by a fulcrum pin 29 with the standard 3. Said lever is connected with the toggle by a link 34 engaged at. one end with the knuckle pin or pivot 26 of the toggle, and at the other end with a pivot 35 carried by the lever 31, and preferably by ears 32 projecting from the lever so that the pivot 35 is offset as shown by Figs. 1 and 2.

The inner toggle pivot 28 and the lever fulcrum pin 29 are in a plane at an angle to the base 1,. and the arrangement of the described parts is such that a movement of the lever 31 to the position shown by Fig. 2 forces the toggle to a position of rest with its links radically out of alinement with each other, and retracts the movable jaw from the fixed jaw, thus opening the jaws.

A movement of the lever to the position shown by Fig. 1 forces the toggle to its active position with its links in or approximately in alinement with each other, and projects the movable-jaw toward the fixed jaw, thus closing the jaws.

It will be seen by reference to Figs. 1 and 2 that when the lever 31 is in its jaw-opening position the pivot 35 is at one side of the plane in which the inner pivot 28 and fulcrum 29 are located, and thatwhen the lever is in its jaw-closing position the pivot 35 is scribed position by its own'weight, which is. sufficient to prevent the toggle knuckle from moving toward its position of rest. The le- 1 ver therefore confinesthe toggle in its active at the opposite side of said plane, as shown by Fig. 1. The lever'is held in the last deposition and maintains any closing ressure that may have been imparted. by t e lever through the link and toggle to the movable jaw. The confining action, caused simply by the movement of the lever from one position to the other, is automatic.

The vise may be conveniently adjusted to hold different sizes of pipe by varying the length. of. the turnbuckle link of the toggle. I The hand lever may be of the bell-crank form shown by Fig. 9, in which 31 represents the longer-arm and 37 the shorter arm, the ears 32, which hold the pivot 35, being formed on the shorter arm.

Having described my invention, I claim:

1. A vise comprising a base having a fixed jaw, and a fixed standard s aced from said aw, a movable jaw sliding y engaged with the base between the fixed jaw and the standard, a toggle connected by an outer pivot with the movable jaw and by an inner pivot with the standard, and manually 0perated means for forcing the toggle to a position of rest with the jaws opened, and to an active position with the jaws closed, said means having provisions for automatically confining the toggle in its active position.

2; A vise comprising a base having at one end portion a fixed jaw and at the opposite end portion a fixed standard, a movable jaw slidingly engagedv with the base between said fixed jaw and standard, a toggle connected by an outer pivot with the movable jaw and by an inner pivot with the stand ard, said outer and inner pivots being on a plane substantially parallel with the base, a and lever fulcrumed on the standard at a distance fronnthe said inner pivot, the lever fulcrlun and inner pivot bein on a plane at an angle to the base, and a hnk pivoted at one end to said lever and at the op osite end to the toggle knuckle and'adapte to cooperate with the lever in forcing the tog le to a position of rest with the jaws opene and to an active position with the jaws closed, the arrangement bein such that the weight of the lever is adapte to confine the toggle in its active .position.

3. A vise comprising a base having a fixed jaw and a fixed standard spaced from. the fixed jaw, a movable jaw slidingly engaged with the base between the fixed jaw and the standard, a toggle connected by an outer pivot with the movable jaw and by an inner pivot with the standard, and means for forcing the toggle to a position of rest, with the jaws opened, and to an active position with the jaws closed, the toggle being adjustable in length to vary the closing movement of the movable jaw.

4:. A vise comprising a. base having a fixed jaw and a fixed standard spaced from the fixed jaw, a movable jaw slidingly engaged with the base between the fixed aw and the "standard, a toggle connected by an outerpivot with the movable jaw and by an inner pivot with the standard, and means for forcing the toggle to a position of rest, with the jaws opened, and to an active position with the jaws closed, one of the toggle links being a turnbuckle adapted to vary the length of the toggle.
